a second extension that is bent from the first extension and that extends in a direction perpendicular to the rear surface of the front panel; and a third extension that is bent from the second extension and that extends toward the first surface of the at least one of the pair of side frames in a direction opposite to the first direction, and wherein the wire guide defines an accommodation space that is surrounded by the first, second, and third extensions and that is configured to accommodate the wire therein. ### Claim 4 (depends on 3) The cooking appliance of claim 3, wherein the third extension extends in parallel to the first extension, and has an end that is spaced apart from the first surface of the at least one of the pair of side frames and that defines a path configured to allow insertion of the wire to the accommodation space. ### Claim 5 (depends on 4) The cooking appliance of claim 4, wherein the at least one intermediate panel covers at least a portion of the path. ### Claim 6 (depends on 5) The cooking appliance of claim 5, wherein the at least one intermediate panel comprises: a first intermediate panel that faces a side surface of the second extension; and a second intermediate panel that is spaced apart from the first intermediate panel and that covers at least the portion of the path. ### Claim 7 (depends on 1) The cooking appliance of claim 1, further comprising a guide frame configured to receive the wire guided by the wire guide and to direct the wire toward the body through a hinge space defined between the plurality of hinge mechanisms. ### Claim 8 (depends on 7) The cooking appliance of claim 7, wherein the body defines a body opening configured to receive the guide frame, and wherein the lower frame is rotatably connected to the guide frame. ### Claim 9 (depends on 8) The cooking appliance of claim 8, wherein the lower frame comprises: a panel support configured to support the at least one intermediate panel and the rear panel; and side frame connection portions disposed at both lateral sides of the panel support, respectively, and wherein the panel support defines a slot configured to receive the wire. ### Claim 10 (depends on 9) The cooking appliance of claim 9, wherein the panel support comprises a guide frame connection portion to which the guide frame is rotatably connected. ### Claim 11 (depends on 10) The cooking appliance of claim 10, wherein the guide frame comprises: a frame body that defines a guide space configured to receive the wire; and a connection body that is configured to rotatably connect the frame body to the guide frame connection portion, the connection body defining a guide opening configured to receive the wire to thereby allow the wire to extend to the guide space of the frame body. ### Claim 12 (depends on 11) The cooking appliance of claim 11, wherein the connection body comprises a first hinge portion having a first diameter, and a second hinge portion having a second diameter that is less than the first diameter of the first hinge portion, and wherein the guide frame connection portion defines a first hinge hole configured to receive the first hinge portion, and a second hinge hole configured to receive the second hinge portion. ### Claim 13 (depends on 9) The cooking appliance of claim 9, wherein each of the plurality of hinge mechanisms comprises a hinge body that is connected to one of the pair of side frames and that passes through the corresponding side frame connection portion. ### Claim 14 (depends on 1) The cooking appliance of claim 1, wherein the wire comprises a first wire and a second wire, and wherein the pair of side frames comprise: a first side frame configured to guide the first wire to the control device; and a second side frame configured to guide the second wire to the control device. ### Claim 15 (depends on 1) The cooking appliance of claim 1, wherein the at least one of the pair of side frames defines a first chamber and a second chamber that extend along the wire guide, and wherein the first chamber is defined at a position between the wire guide and the second chamber. ### Claim 16 (depends on 15) The cooking appliance of claim 15, wherein the second chamber is disposed laterally outward of the first chamber to an outside of the door. ### Claim 17 (depends on 15) The cooking appliance of claim 15, wherein each of the hinge mechanisms comprises: a hinge frame disposed at the body; and a hinge body that is rotatably connected to the hinge frame and that is connected to the first chamber. ### Claim 18 (depends on 15) The cooking appliance of claim 15, further comprising a side decoration member disposed at a side of each of the pair of side frames, wherein the second chamber faces the side decoration member. ### Claim 19 (depends on 1) The cooking appliance of claim 1, wherein the control device is disposed at an upper portion of the door, wherein the wire comprises at least one of (i) a power line configured to supply power from a power source to one or more components of the cooking appliance or (ii) a signal line configured to transmit control signals from the control device to the one or more components of the cooking appliance, and wherein the wire guide is configured to guide the wire from the control device downward to the body. ### Claim 20 (depends on 19) The cooking appliance of claim 19, wherein each of the plurality of hinge mechanisms is disposed at a lower portion of the body, and wherein the wire guide is configured to guide the wire from the control device downward to the lower portion of the body through one of the plurality of hinge mechanisms.
